THONY E. WEINGARTNER, F BETHLEHEM, PENNSYLVANIA, ASSIGNOR TO ERI- CAN ENGINEERING COMPANY, OF PHILADELPHIA, PENNSYLVIA, A CORPORA- TION' OF PENNSYLV Application filed new is, 1925. Serial No. mesa My invention relates to such couplings as are adapted to connect a driving shaft and a driven shaft.

One object of my invention is to provide a device of the class described which shall be characterized by simplicity of desi n, and inexpensiveness and case of assem 1y with or removal from its associated parts.

A disadvantage of the prior art couplings of the above-noted type is that when the driving shaft is to be disconnected from the driven shaft, one or the other of these shafts must be bodily removed, thus causing a greatloss in time and consequent difiiculties in maintenance and operation. Another object of m invention, therefore, is to provide a separa 1e couplin that shall avoid these dificulties and stille relatively simple and inexpensive. j

Other objects and applications of myinvention, as well as details of construction and operation, whereby my invention may be practiced, will appear more fully hereinafter, when taken in connection with the accompanying drawings, wherein i Fig. 1 is a longitudinal sectional view of one form of embodiment of my invention with the coupling disk in interlocking en-' vgagement with the associated coupling sleeves;

Fig. 2 is a similar view but showing the movable coupling sleeve in its disengaged.

position, permitting the removal or the replacement of the coupling disk; and

Figs. 3, t and 5 are detached perspective views of certain of the coupling elements of Figs. 1 and 2. 7

In the illustrated embodiment of my invention shown in. the drawings, sleeves 1- and 2 of a separable coupling 3 are keyed or otherwiserigidly secured to shaft end portions 4 and 5, respectively. The position of sleeve 2 may be further secured by means of a set screwe'i extending from said sleev into engagement with a key .7.

-A third sleeve 8 is slidablymounted on the fixed sleeve 2 and it may be secured against circumferential movement by means (it an axially extending key 9. The sleeve 8 is provided with a perforation 10 which registers with the set screw 6 whenthe couplmgis in the closed oreflective osition of ad to the.

Fig. 1, whereby access may be set screw 6 should it, be desirable the position of the sleeve 2 on the shaft end portion 5.; The bore'of the axially movable sleeve 8 may be enlarged at 11 (Figsrl and 4) to form a shoulder 13, the latter being movable into engagement with an annular flange 14 (Fig. 1) formed on the inner end to adjust of the sleeve 2 when the movable sleeve 8 is 1n lts innermost or interlocking position shown in Fig. 1.

The sleeve 8 may be actuated by means of cular flange 17 of the nut 15. Thus it is ap aste that the turning of the nut in one direction causes a movement of thesleeve 8 from the etlective position shown in Fig. 1 to the inefiective positon shown in Fig. '2, but areverse movement of the nut 15 causes the sleeve 8 to be returned to its ori inal position, all as will appear more fully ereina'fter.

The 'fixed sleeve 1 and the movable sleeve 8 may be mechanicall interconnected by means of a coupling dISk 24 having a slot 25 extending across one face 26 thereof. An opposite face '27 .is provided with recesses 28 and 29, which extend radially inwardly a short distance, as shown in Fig. 1. One advantage of thus partly extending the recesses 28 and 29 across the face 27 of'the coupling disk 24 is that a relatively thin coupling disk .may be employed without weakening the central portion thereof. The slot 25 is adapted to receive spaced lugs 31 and 32 (Figs. 1 and 3) which extend from an adjacent tace 33 of the fixed sleeve 1. Similarly the recesses 28 and 29 are adap to receive sleeve 2. One edge ofthe nut I coupling disk 24.

34 and 35, (Figs. 1 and 4) respectively w ich extend from an adjacent face 36 of the movable sleeve 8.

In order to prevent the coupling disk 24 from vibrating during normal operat on,I provide a lurality of perforations 37 inthe k 24, said perforations having countersunk portions 38. A plun er 39 is 'tioned in eachperforation, wh e an enmed head portion 41 thereof is disposed in the countersunk portion 38 of said rforation. A s ring 42, which extends tween the base the countersunk portion 38 and the enlar ed head portion 41, serves to cause a round outer face 43 of the head portion 41 to engage resiliently the adjacent face 33 of the fix coupling sleeve 1. The face 27 of the coupling disk 21 is also caused to enresilientl the adjacent face 36 of the movable coup ing sleeve 8 and thus any tendenc for the coupling disk 24to vibrate is y 'min' ssuming the arts in the position shown in Fig. 1, when it is desired to remove the coup disk 24, a set screw 44, which serves to rigi y secure the nut n positionis loosened and thereafter said nut is turne so as to cause the sleet'e 8 to move into the tion shown in-Fig. 2. The coupling dis 24 ma now be disengaged from the sleeves 1 and 8 and readily removed without in any way disturbing the shaft endportions 4 and 5, as would be necessary with the prior art couplings. When it is desired to bring the parts again into the interlocked position shown in Fig. 1, the coupling disk 24 is replaced and the nut 15 is actuated in an opposite direction until the shoulder 13 thereof engages the annular flange 11 of the rigid sleeve 2, in which position of the sleeve 8,

are respectively disposed the lugs 34 and 28 and 29 of the coupling in the recesses While I have shown only one embodiment of my invention, for the purpose of desa'ibing the same and illustrating its principles of construction and operation, it is apparent that various changes and modificadesire, therefore, that tions may be made therein ivithout departing from the spirit of my invention, and I be made thereon as are indicated in the appended claims or as are demanded by the prior art.
